Troubleshooting

Modify the MySQL data directory

Before running the commands shown on this page, you should load the Bitnami stack environment by executing the installdir/use_APPNAME script (Linux and MacOS) or by clicking the shortcut in the Start Menu under “Start -> Bitnami APPNAME Stack -> Application console” (Windows). On OS X VMs, the installation directory is /opt/bitnami and OS X VM users can click the “Open Terminal” button to run commands. Learn more about the Bitnami stack environment and about OS X VMs.

NOTE: We are in the process of modifying the file structure and configuration for many Bitnami stacks. On account of these changes, the file paths stated in this guide may change depending on whether your Bitnami stack uses native Linux system packages (Approach A), or if it is a self-contained installation (Approach B). To identify your Bitnami installation type and what approach to follow, run the command below:

NOTE: The DB_VOLUME_DIR environment variable is set to /bitnami/mysql.

To change the location of the MySQL data directory, modify the installdir/scripts/mysql-env.sh file as shown below:

...
export DB_DATA_DIR=/bitnami/mysql/data
...

Finally, move the data/ directory to the new location and restart the database.

Approach B: Self-contained Bitnami installations

For self-contained Bitnami stacks, the data directory for MySQL is set located at installdir/mysql/data by default. To change the location of this folder, modify the installdir/mysql/my.cnf file as shown below:

...
datadir=installdir/mysql/data
...

Modify the installdir/mysql/scripts/ctl.sh file to reflect the new directory location:

--datadir=installdir/mysql/data

Finally, move the data/ directory to the new location and restart the database.
